Patent stocks drop following Vringo ruling

|By:, SA News Editor

Worlds (OTCQB:WDDD -15.3%), Spherix (SPEX -5.8%) and Marathon Patent Group (MARA -3.6%) have sold off after a federal appeals court ruled against Vringo in its IP suit against Google, arguing the patent claims it has asserted are invalid due to obviousness.

Notably, the court referenced a recent Supreme Court ruling that upheld the patentability of software concepts that advance or improve upon existing ideas, but also declared mere abstract software ideas on a computer can't be patented.

Spherix is still well above where it traded before an AT&T settlement was disclosed on Monday.
